Dotcase: Fix brightness sticking

The UEventObserver sees the case open, so it turns on the screen and
kills the Dotcase activity. But, then the BroadcastReceiver sees the
screen turn on, so it tries to launch the Dotcase "stuff," including
setting the brightness to max. Sometimes, the order in which these
things happen causes the brightness to get set to max after the
activity is killed, and it gets stuck there until the case is closed
and opened again.

Make the switchState a class variable and, in the BroadcastReceiver,
check whether the case is open before starting any of the Dotcase
stuff.

Dotcase: Improve exception-handling

Don't catch generic Exception, and log exceptions as errors. Also,
remove try-catch blocks around things which seemingly do not throw any
exception.

Dotcase: Only check for new notifications before displaying them

Rather than check for new notifications on every redraw, only check at
the beginning of each animation cycle (i.e., right before they're
about to be shown). This reduces notification checks from about twice
per second to about every 3 seconds.
